Welcome. You're a smart man if you used to be on DSMtuners and even smarter to come to EVOtuners now that you have the best Evo possible - the IX MR. I used to live in NOVA (Sterling), so I participated in the SCCA WDCR region as well as the Capital Driving Club (smaller, local, non-classed auto-x club) and NASA Mid-Atlantic, but I moved to CO and run with the SCCA and NASA Rocky Mountain regions now.
Feel free to ask tech questions and pick our brains. We aren't interested in bs, loud BOVs, ricer mods, sound, or looks except for when those things are in the context of racing and making the Evo a better car, so keep all that in mind. We are here to answer and discuss serious tech topics that relate to the Evo, so let 'er rip!
